Page 1 of 10 <br />SOP NUMBER 8.0 Field Parameter Measurements <br />1.0 PURPOSE AND SCOPE <br />This standard operating procedure (SOP) describes procedures that will be used to obtain field <br />parameter measurements for surface water and groundwater parameter samples. These <br />parameters are pH, temperature, specific conductivity (S.C.), dissolved oxygen (D.O.), oxidation <br />reduction potential (O.R.P), and turbidity. This SOP describes field measurement procedures, <br />personnel responsibilities and qualifications, and quality assurance/quality control (QA/QC) <br />procedures. <br />2.0 RESPONSIBILITIES AND QUALIFICATIONS <br />The Project Manager or Field Manager has the overall responsibility for implementing this SOP. <br />They will be responsible for assigning appropriate environmental staff to implement this SOP <br />and for ensuring that the procedures are followed by all personnel. <br />All personnel performing these procedures are required to have the appropriate health and safety <br />training. In addition, all personnel are required to have a complete understanding of the <br />procedures described within this SOP and receive specific training regarding these procedures, if <br />necessary. <br />All environmental staff and assay laboratory staff are responsible for reporting deviations from <br />this SOP to the Project Manager or Field Manager. <br />3.0 RELATED STANDARD OPERATING PROCEDURES <br />The procedures for field measurements set forth in this SOP are intended for use with the following <br />sops: <br />SOP No. 1.0 Surface Water and Seep Sampling <br />SOP No. 26.0 Groundwater Sampling <br />SOP No. 10.0 Decontamination of Sampling Equipment <br />4.0 EQUIPMENT LIST <br />In addition to the equipment cited in associated SOPS for the collection of surface and <br />groundwater samples (SOP Nos. 1.0 and 26.0, respectively), the following meters which are the <br />current equipment available, or their equivalent, are required for the implementation of this SOP. <br />pH meter with a temperature scale (Geotech Multiline P3 pH/LF with integrated SenTix41 <br />pH/temperature probe) <br />Specific conductivity meter ( pH/LF standard conductivity cell ) <br />Dissolved oxygen meter (pH/OXI Dissolved oxygen probe with air calibration beaker Oxical - <br />SL) <br />Oxidation Reduction Potential meter (pH/OXI with UAg/AgCI redox electrode probe) <br />Powertech <br />4/23/2007 <br />Rev SOP 8-1 JAB <br />8-1 <br />R Squared Inc <br />
